[j-nsp] DiffServ MPLS on MX80

[Cydon Satyr]

I am trying to switch to diffserv model (mam) from non-diffserv model, but
for some reason LSPs won't establish.
I added

diffserv-te {
    bandwidth-model mam;
}

to mpls stanza, as well as tried to reserve bandwidth with

{
    bandwidth ct1 25m;
}

in lsp stanza.

RSVP/MPLS/OSPF with traffic engineering is enabled. I'm not sure what I'm
missing, I followed documentation. When troubleshooting with traceoptions,
I see messages:

" link is not diffserv capable: ignoring"

Is there something else that needs to be added to configuration?

Thanks
